We present a 3-D microwave breast imaging study in which we reconstruct the dielectric profiles of MRI-derived numerical breast phantoms from simulated array measurements using an enclosed array of multiband, miniaturized patch antennas. The array is designed to overcome challenges relating to the ill-posed nature of the inverse scattering system. We use a multifrequency formulation of the distorted Born iterative method to image four normal-tissue breast phantoms, each corresponding to a different density class. The reconstructed fibroglandular distributions are very faithful to the true distributions in location and basic shape. These results establish the feasibility of using an enclosed array of miniaturized, multiband patch antennas for quantitative microwave breast imaging.

使用封闭式多波段、小型贴片天线阵列对真实数字乳房模型进行定量微波成像

我们提出了一项 3-D 微波乳房成像研究，在该研究中，我们使用封闭式多波段、小型贴片天线阵列从模拟阵列测量中重建 MRI 衍生的数值乳房模型的介电分布。该阵列旨在克服与逆散射系统不适定性质相关的挑战。我们使用失真的 Born 迭代方法的多频公式对四个正常组织的乳房模型进行成像，每个模型对应于不同的密度类别。重建的纤维腺体分布非常忠实于位置和基本形状的真实分布。这些结果确立了使用封闭式微型多频带贴片天线阵列进行定量微波乳房成像的可行性。
